  • Publication number: 20040146620
    Abstract: The present invention provides a method of sterilizing a food packaging container or a food charging system, which comprises a chemical sterilizing treatment which involves contacting an aqueous sterilizing solution containing a hypochlorous acid-containing, chlorine-based sterilizing agent and a pH adjusting agent with the surface of a food packaging container or the surface of a line pipe, an instrument and a chamber in a food packaging system and a heat sterilizing treatment which involves increasing the temperature of the surface to be sterilized, the two sterilizing treatments being carried out simultaneously or in separate steps. The invention also provides a sterilizing device which has a predetermined sterilizing effect on a wide variety of microbial species, can be easily handled, does not corrode a treated surface over a prolonged period of time, is free of a pungent smell and does not require any special treatment for disposal of waste liquor.
